A minor point of clarification (admittedly rather pedantic though in line with the many comments in this discussion which relate to scientific rigor) but the statements indicating lichen sourced D3 is plant-based can be misleading. While many lichens contain one or more algae species/strains (hence containing a plant) some do not. Some lichens contain cyanobacteria as their sole photosynthesizing member in symbiosis with fungi (ie. no plant involved.) I don't know the specifics of the lichen source for vitamin D3 production. So a plant may or may not be involved.

Based on vitamin D being produced by other fungi than lichens and no (known to me) plant source of D3 I'll venture a guess that the source of the D3 in lichens is from the fungal component. If this holds true then claiming lichen sourced D3 is plant-based is a bit of a stretch.

Of course a popular reading of "plant-based" as used in current diet marketing -which seems to mean anything not derived from an animal- could hold. But marketing speak is anything but scientific.

[Quick searches didn't lead me to clarity on whether algae are part of the lichens used for commercial D3 production. I do wonder why lichens were chosen over mushrooms. I'd have thought mushrooms would have multiple advantages.]

Business:

VisiCalc came out in 1979, and spreadsheets were common in business offices in the U.S.A. through the 1980's.

Entertainment - TV and movies:

Computers were also used in commercial and movie production (ex. the 1984 Macintosh commercial, Pixar founded 1986 more or less out of Lucasfilm, and note that the VideoToaster came out for the Amiga in 1990 bringing professional level video production to a much more accessible price point.)

How I learned the Unreadable: “Sometimes writing for money -rather than for art or pleasure- is really quite enjoyable.”

To the teacher I learned from this was a standard way of punctuating on a typewriter.

Our 2013 Prius just had the center-dash unit crash likely due to the audio sub-system. And it would have burned but for a fuse blowing (replacing the fuse lead to smoking.) This took out the rear camera display along with climate controls, audio, ...

Fortunately someone at the Toyota shop we patronize had just replaced their same model year working unit with an iPad (hence learned that's a thing in the US even if illegal in the UK.) So what was going to be a ~$2,000 USD rebuilt unit (~$5,000 OEM new but a guy in town rebuilds them because there is apparently enough demand) was going to be less expensive.

Unfortunately, our Prius's unit seems to be unique to a particular finish/package for the model. And this particular unit type (a JBL variant) has connectors different from all other Toyota center console units.

Gist of the situation: failure of what is likely the audio section of the integrated center-dash unit took out rear camera, climate controls, audio, etc. with high price tag to repair when simple loss of audio unit would have been ignored.

Spreadsheet rules (or formulas) in The Analyst are kept as Smalltalk blocks. A block is a common Smaiitalk object class which allows a section of compiled code to be kept as an object. They can be passed as arguments and stored as variables. Obviously, they are an ideal choice for rule storage and execution, since they allow the rules to be directly executed by Smalltslk at compiled speeds.

The description of ASP (and the Analyst package from which it was split out as a separate product) can be found at http://www.bitsavers.org/pdf/xerox/xsis/XSIS_Smalltalk_Produ... . Of interest is the example of dropping a bitmap image into a cell and having an adjacent cell display the next generation of the game-of-life run on that initial cell. (That as opposed to having each spreadsheet cell in a region represent a cell in a game-of-life automata.)

As to homoiconicity, I wouldn't be surprised if Alan didn't at some point have a Smalltalk project window running full screen that was imbedded in a cell of a spreadsheet which was running in a Smalltalk project window within the Smalltalk environment. It's the kind of thing I saw him demonstrate as an aside during presentations as he popped out of the full screen project window which the audience had assumed was the root Smalltalk environment rather than a nested environment. What is a cell or window but a live code object running in the language environment after all?

I've never tried Ginko kernels roasted to the point they were crunchy. But I find the ones roasted (some times on a skewer) to the consistency of firm cooked lima beans have a flavor similar to lima beans. Preparing lima beans is much easier though they produce very different medicinal effects.

1) The night owl's late to bed and late to rise (first military watch)

2) The Dagwood Bumstead early to bed, up in the middle of the night, late to rise (second military watch)

3) Poor Richard's "Early to bed and early to rise" (third watch)

It was theorized that the three military watches possibly arose from prehistoric humans in small bands gaining survival advantages from having subsets of group members awake throughout the night.

I should also mention that long standing human practices involving nights when groups went without sleep showed up around the globe were studied as well. These existed independent of and seemingly well before showing up in academic settings and post industrial workplaces.

It was a truly open source project within the VA with programmers customizing this national patient record software in cooperation with doctors (to meet their needs) locally and sharing the modifications nationally. Perhaps its greatest technical challenge (besides complexity arising from decades of evolution) was finding programmers to work with the MUMPS language that it was written in. FYI MUMPS is a language with an integral db -a concept which was out of vogue for some time.

Political challenges are another story[4].
